A man who had his best friend's teeth embedded in his leg in an accident on a trampoline is suing a hospital for failing to remove them.

Daniel Rigby, of Pollards Hill, south London, has suffered debilitating knee swelling since the incident in March following which he says Croydon University Hospital failed to fully remove the three teeth which have caused the infection.

The 29-year-old was lying on his trampoline on FaceTime on his iPad at about 10am, when best friend, Peter Walsh, who had been drinking, came over to join him.
